Five deaths in Florida blamed on Matthew

Authorities say an elderly couple appears to have died from carbon monoxide poisoning while running a generator after Hurricane Matthew, raising the U.S. death toll from the storm to 5.

A post on the St. Lucie County Fire District's Facebook page says rescuers responded to couple's home Friday morning after neighbors found them not breathing. They were taken to a nearby hospital, where county spokesman Erick Gill says they later died.

Officials say the couple had been running a generator inside their garage throughout the storm.

Officials didn't immediately name the couple.

The Putnam County, Florida, Sheriff's Office reported Friday that a woman was killed and a man was injured near Crescent City when a tree fell on their camper during the storm.

A post on the sheriff's office Facebook page says the two adults were attempting to ride out the storm when high winds apparently caused the tree to fall. The man escaped with minor injuries, but the woman was killed.

Authorities didn't immediately name the victims.

Earlier Friday, Volusia County emergency management director Jim Judge reported the death of a woman after a tree fell on her house.
